Attaching track to foamboard?

[RobertInOntario]

You can, as it is great for joining dissimilar materials (as well as foam to foam). But it does get kind of bubbly, so you'll want to make sure that it doesn't expand up and over your ties/track.
Whatever you do, be sure to take pictures for us!

Thanks, Andrew. I was thinking of only using a few very small drops of this glue. I think that would be sufficient to hold the track.

Sure, I'll post some pix in due course. Right now, the layout doesn't look much different than it did a few months ago. I've tweaked the track & added a passing siding, but haven't done much scenery yet. I plan to get to that in the fall/winter.

Actually, I'm in a bit of a quandary with the scenery because I want to keep the layout simple for storage, etc. Also, because it's such a small layout, I'm running out of room to put things! For example, I'm running out of space to have a road running across the layout. It seems that no matter where I put it, the road ends up having to cross the tracks at unsuitable places, i.e. at turnouts or interfering with my station area. I also have a really neat footbridge crossing the tracks but even that is taking up too much space, interfering with sidings, not being wide enough, etc.

I'll keep working at this and I'll post pics, as and when I come up with solutions and finish scenery.
